Dear Guvenc,<br><br>if I understood your question correctly, this might be a way to get what you want:<br>when you save the residual as &quot;chi(k)&quot; you probably get a two column file where column 1 is &quot;k&quot; and column 2 is &quot;chi(k)&quot;. If you are saving the residual plus data and fits you will have more than two columns in the file, but it shouldn&#39;t be hard to identify which is the residual. Open this file in a spreadsheet program (such as Origin, Igor, Excel, etc) and then create a new column, setting its values as [((column&quot;k&quot;)^3)*(column&quot;residual chi(k)&quot;)]. That should allow you to plot the k-cube-weighted residual as a function of k. Was that your goal?<br>

dear all,<br>
<br>
I need save residual as k^3*Chi(k) but I could not save it because it is saving only as Chi(k).how can do for this?<br>
<br>
thanks in advance<br>
